Description

La présente invention concerne le domaine des accessoires de véhicules automobiles, en particulier des lave-glaces, et a pour objet un lave-glace à deux réservoirs de liquide.The present invention relates to the field of motor vehicle accessories, in particular windshield washers, and relates to a windshield washer with two liquid reservoirs.

Actuellement, les lave-glaces pour véhicules automobiles sont généralement constitués par un ou plusieurs gicleurs reliés par l'intermédiaire d'une pompe à un réservoir de liquide de lavage. Ces lave-glaces connus permettent, par remplissage de leur réservoir avec un liquide adapté, un lavage correct des pare-brises, ou autre. Cependant, en été pour débarrasser un pare-brise des moucherons écrasés, ou en hiver pour dégivrer ledit pare-brise, une faible quantité de liquide approprié serait suffisante, et la majeure partie dudit liquide utilisé sert uniquement au rinçage. Ainsi, pour obtenir un pare-brise propre, l'utilisateur est conduit à une dépense relativement importante de liquide de lavage, souvent dissuasive.Currently, windshield washers for motor vehicles generally consist of one or more nozzles connected by means of a pump to a reservoir of washing liquid. These known windshield washers allow, by filling their reservoir with a suitable liquid, a correct washing of the windshields, or the like. However, in summer to rid a windshield of crushed midges, or in winter to defrost said windshield, a small amount of suitable liquid would be sufficient, and most of said liquid used is used only for rinsing. Thus, to obtain a clean windshield, the user is led to a relatively large expenditure of washing liquid, often a deterrent.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un lave-glace, caractérisé en ce qu'il est constitué par deux réservoirs à liquide séparés munis chacun d'une pompe électrique, et reliés aux gicleurs de lave-glace par l'intermédiaire d'un raccordement en té avec interposition, entre le raccordement en té et chaque pompe d'un anti-retour, et par un organe de commande différentielle des pompes électriques.It has, in fact, for a windshield washer, characterized in that it is constituted by two separate liquid reservoirs each provided with an electric pump, and connected to the windshield washer nozzles by means of a tee connection with interposition, between connection at the tee and each pump with a non-return, and by a differential control member for the electric pumps.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donne à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est un schéma de principe d'un gicleur conforme à l'invention.The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a diagram of principle of a sprinkler according to the invention.

Comme le montre le dessin annexé, le lave-glace conforme à l'invention est essentiellement constitué par deux réservoirs à liquide 1 séparés, qui sont munis chacun d'une pompe électrique 2, et qui sont reliés aux gicleurs 3 de lave-glace par l'intermédiaire d'un raccordement en té 4. Entre le raccordement en té 4 et chaque pompe 2 est monté un anti-retour 5, et une commande différentielle des pompes 2 est réalisée au moyen d'un organe 6.As shown in the appended drawing, the windscreen washer according to the invention essentially consists of two separate liquid reservoirs 1, which are each provided with an electric pump 2, and which are connected to the windscreen washer nozzles 3 via a tee connection 4. Between the tee connection 4 and each pump 2 is mounted a non-return 5, and a differential control of the pumps 2 is carried out by means of a member 6.

Les réservoirs à liquide 1 renferment chacun un liquide distinct, à savoir un liquide de lavage et un liquide de rinçage, par exemple un liquide anti-moustique et de l'eau en été, ou un liquide anti-givre et un liquide antigel de rinçage en hiver.The liquid tanks 1 each contain a separate liquid, namely a washing liquid and a rinsing liquid, for example a mosquito repellent liquid and water in summer, or an anti-frost liquid and a rinsing antifreeze liquid in winter.

L'organe 6 de commande différentielle des pompes électriques 2 est avantageusement sous forme d'un temporisateur mis en circuit directement ou au moyen d'un relais 7 actionné par une manette de commande usuelle 8, et présentant deux contacts 9 et 10 à mises sous tension et hors tension différées des pompes électriques 2. Ainsi, le contact 9 peut, par exemple, être mis sous tension en premier et permettre le fonctionnement de la pompe 2 reliée au récipient 1 renfermant le liquide de lavage, sa coupure correspondant à la mise sous tension du contact 10 de commande de pompe 2 reliée au récipient 1 renfermant le liquide de rinçage.The differential control member 6 for the electric pumps 2 is advantageously in the form of a timer connected directly or by means of a relay 7 actuated by a conventional control lever 8, and having two contacts 9 and 10 to be put under deferred power on and off of the electric pumps 2. Thus, the contact 9 can, for example, be switched on first and allow the operation of the pump 2 connected to the container 1 containing the washing liquid, its cut off corresponding to the setting under voltage of the pump control contact 10 connected to the container 1 containing the rinsing liquid.

Le temporisateur 6 est un temporisateur électro-mécanique ou électronique, dont la durée de mise sous tension du premier contact est règlable, le second contact étant coupé lors du relâchement de la manette de commande 8.Timer 6 is an electro-mechanical or electronic timer, the duration of which the first contact is energized is adjustable, the second contact being cut when the control lever 8 is released.

Selon une autre variante de réalisation de l'invention, non représentée au dessin annexé, l'organe 6 de commande différentielle des pompes électriques 2 peut être constitué sous forme d'un interrupteur manuel à deux positions à retour automatique en position de repos.According to another alternative embodiment of the invention, not shown in the accompanying drawing, the member 6 for differential control of the electric pumps 2 can be constituted in the form of a manual switch with two positions with automatic return to the rest position.

Conformément à une autre variante de réalisation de l'invention, non représentée au dessin annexé, les anti-retours 5 et le raccordement en té peuvent être remplacés par une vanne à trois voies-deux positions dont la sortie est reliée aux gicleurs 3, et dont les entrées sont raccordées aux pompes 2 des réservoirs 1. Dans le cas d'utilisation d'une telle vanne, la mise en marche de la première pompe a pour effet de fermer l'orifice d'entrée de vanne correspondant à la deuxième pompe, et inversement.In accordance with another alternative embodiment of the invention, not shown in the accompanying drawing, the non-return valves 5 and the tee connection can be replaced by a three-way valve with two positions, the outlet of which is connected to the nozzles 3, and the inputs of which are connected to the pumps 2 of the reservoirs 1. If such a valve is used, switching on the first pump has the effect of closing the valve inlet orifice corresponding to the second pump , and vice versa.

Le lave-glace conforme à l'invention fonctionne de la manière suivante :

  • Par actionnement de la manette 8, le relais 7 met le temporisateur 6 sous tension et le premier contact 9 est fermé pendant un temps prédéterminé,.par exemple d'une durée de trois secondes. La première pompe 2, reliée au réservoir 1 de liquide de lavage est alors mise en marche et débite ledit liquide pour l'éjecter à travers les gicleurs 3. Le liquide sous pression, qui est transporté à travers le raccordement en té 4, ferme la conduite d'amenée affectée à l'autre réservoir 1 en poussant sur la bille de l'anti-retour 5 correspondant. Après écoulement de la durée prédéterminée, le temporisateur 6 coupe le contact 9 et met le contact 10 sous tension et ainsi la deuxième pompe 2, qui débite alors le liquide de rinçage qui ferme l'anti-retour 5 affecté au premier réservoir 1. Cette deuxième pompe débite du liquide de rinçage tant que la manette 8 est actionnée. Dès que cette dernière est relâchée, le relais 7 coupe le temporisateur 6, qui revient automatiquement en position de départ.
The windscreen washer according to the invention operates as follows:
  • By actuation of the lever 8, the relay 7 energizes the timer 6 and the first contact 9 is closed for a predetermined time, for example of a duration of three seconds. The first pump 2, connected to the reservoir 1 of washing liquid is then started and delivers said liquid to eject it through the jets 3. The pressurized liquid, which is transported through the connection at tee 4, closes the supply line assigned to the other tank 1 by pushing on the ball of the corresponding non-return 5. After the predetermined period of time has elapsed, the timer 6 switches off the contact 9 and switches on the contact 10 and thus the second pump 2, which then delivers the rinsing liquid which closes the non-return valve 5 assigned to the first tank 1. This second pump delivers flushing liquid as long as the handle 8 is actuated. As soon as the latter is released, the relay 7 cuts the timer 6, which automatically returns to the starting position.

Grâce à l'invention, il est possible de réaliser un lave-glace permettant successivement un lavage et un rinçage du pare-brise avec une dépense minimum de liquide de lavage concentré. De plus, l'utilisation d'un liquide de rinçage permet de débarrasser le pare-brise de toutes traces de concentré subsistant nécessairement avec les produits et lave-glaces connus. En outre, en hiver, il est possible de remplir les différentes conduites du lave-glace de produit anti-givre, évitant ainsi toute obstruction de ces dernières.Thanks to the invention, it is possible to carry out a windscreen washer successively washing and rinsing the windshield with a minimum expenditure of concentrated washing liquid. In addition, the use of a rinsing liquid makes it possible to rid the windshield of all traces of concentrate necessarily remaining with the known products and windshield washers. In addition, in winter, it is possible to fill the various lines of the windscreen washer with anti-icing product, thus avoiding any obstruction of these.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
